Be it known that I, OWEN B. BRIGHAM, of Cambridge, in the county of Middlesex, and Stateof Massachusetts, have invented an Improved Snap for Glass-Ware Makers; and I do hereby declare that the following, taken in connection with the drawings which accompany and form partof this specification, is a description of my invention sutlicient to enable those skilled in the art to practise it.

In the manufacture of goblets and other similar articles of glass-ware, it is customaryfor the workman to AA i A, hold the goblet (in finishing the bowl) in an instrument called a snap, or snap-dragon, composed of two fi clamping-disks held normally together by a spring, one disk being slit to its centre, for the introductionof theA t leg or stem of the bowl, and the .other having a. handle by which it is drawn away from the-first, the base of the A i goblet being slipped between the disks (when separated) by passing the leg into the openingin the outer disk,

A, A l the' spring then closing the disks upon the base, and holding the goblet firmly with thebowhand the stem or leg i i projecting Out beyond the instrument in convenient position for finishing the bow'l'. A description of such an;

instrument may be found in United States Letters Patent, No. 17,960. i

My invention relates to certain improvements in .the constructionV of these Asnaps or gobletand other glass-ware holders, the object of my improvements being to provide for the more secure and steadyrholding of` the article than is afforded by such holders as are now in common use. i

In my construction I employ an auxiliary disk, making the disk or plate against which the base of` the goblet is supported and the outer disk or plate bothstationary, and `placing a movable `clamping-disk between these, this clamp-plate being drawn towards the lower one by-a suitable spring. i i i l It is in this arrangemenhland in the peculiar constructionfff -the outer disk or plate ilgsuch inannuithat` the bowl of the goblet is directly-supported'thereby,that my invention' consists. u l p A A AA The drawings represent a glass-ware fsnap embodying my invention, VA showing an elevationfand B a 3 central section of the same. A i t A a denotes a disk or bed-plate, fixed upon the end of a rod, b, and having its outer surface preferably ni'ade witha circular recess or bed, c, for centring a goblet or `other article, d, to be held in the snap. On oppositel sides of this bed-plate a are pillars e, upon which is fixed and supported another disk or plate,f, the two plates# A a andf being relatively stationary. The platef has a radial opening, g, extending from one sideAto its centre,`;` to permit insertion of the stem or leg 7L of thegoblet in introducing the base tinto the snap. V:Between the W A plates a'f is a movable or Vclamping-disk -or plate, k, which slides on the pillars e, and is supported onarms l, i projecting from a hub or ring, m, fixed to a. stem, n, running through the rod b; a spring, c, serving to draw ,l the clamp-plate k down towards the bed-plate a, as will be readily understood. The clamp-plate has airadial AA 1 i opening, p, (to receive the goblet-leg 71,), in line with the opening g.

In plaeingaI goblet in the'snap, the plate lc is pushed away from the bed-plate a, the Abase z' is then carried` in between the plates a and c(the leg 7L passing through lthe slots or Openings g 2),) and the goblet `is thenheld stationary (with respect tothe disks a and' f) for the platelc to spring down and clamp the based' to the bed-plate.

It will be observed that by this arrangement the goblet is first positioned in the snap, and is not then moved in grasping it by the clamp, the leg being thereby more securely protected, and being less liable to break. i p

For the better support of the leg, and the bottom part of the bowl r of thegoblet, I make the upper plateA fwith a neck, q, .which extends up to the bowl, the base of the bowl resting directly upon its top, as seen in the drawings, the length of the goblet-foot and leg, from the bottom of the bowl to the u'nder surface ofthe baser', l i 1 A corresponding to the distance from the upper surface of,I the bed-plate to the top lof the neck i With a snap so made,4a goblet can' be much more safely and freely handled in finishing it, and far fewer will be brbken than in employing those in common use. A

I claim, in combination with the fixed plates a and f, the clamp-plate k, so constructedand arranged thatA the base of the goblet is clamped down against the bed-plate, substantially as described. All Also, in combination with the plate f, the neck 1', for directly supporting the goblet-bowl, substantially as set forth. A l. u OWENE. BEIGHAM.
